Presented by

Stephen Lerner
  • SANS OSINT Summit 2025

This talk will be broken into three parts.

  • Part I: Attendees will learn how to extract friends and following/followers list from various social media platforms (Facebook, Instagram, Twitter, Gab, etc).
  • Part II: We will then go over how to clean and prepare the extracted data for upload to GEPHI. GEPHI is a free to install graphing tool.
  • Part III: We will show how to install and use GEPHI to create social network graphs. Attendees will come away with having learned a tangible skill that they can immediately put into practice for social media investigations.
